Fluid filled attachment device

ABSTRACT

An attachment device is provided comprising at least one fluid filled cavity formed therein. The attachment device is preferably in the form of a carabiner in which at least a portion of the carabiner body is formed of a transparent material such that the fluid filled cavity is visible. In a preferred embodiment an indicia bearing means is visibly disposed within said cavity.

This application is a divisional of application Ser. No. 10/444,225, filed May 23, 2003, U.S. Pat. No. 7,353,571, issued Apr. 8, 2008, and this application incorporates by reference herein the entirety thereof.

FIELD OF THE INVENTION

The invention relates generally to attachment devices having a fluid-containing cavity.

BACKGROUND OF THE INVENTION

Attachment devices such as snap hooks and carabiners have long been in use for providing a means for attaching articles to each other. Such devices have numerous applications, such as for example enabling multiple articles to be secured to a backpack, purse, handbag, key chain or the like. As such, these devices are fairly ubiquitous. An example of an attachment device is a carabiner such as is disclosed in U.S. Pat. No. 5,005,266.

Fluid-filled ornamental articles are known in the art. For example, U.S. Pat. No. 4,148,199 relates to a pierced earring with liquid visible therein. U.S. Pat. No. 4,093,973 relates to a liquid filled ornamental article of jewelry containing an illumination source. U.S. Pat. No. 5,006,375 relates to an ornamental article having a transparent housing shaped into a decorative configuration having a liquid therein and a subatmospheric pressure area between the liquid and housing. However, none of the prior art liquid filled ornamental articles have the utility of providing a means for attaching articles to each other and providing an indicia bearing means on a ubiquitous useful article.

SUMMARY OF THE INVENTION

The invention provides an attachment device comprising at least one fluid filled cavity formed therein. The attachment device is preferably in the form of a carabiner in which at least a portion of the carabiner body is formed of a transparent material such that the fluid filled cavity is visible. In a preferred embodiment an indicia bearing means is visibly disposed within said cavity.

OBJECTS OF THE INVENTION

It is an object of the present invention to provide a fluid filled attachment device that is aesthetically pleasing.

It is a further object of the present invention to provide a novel attachment device that provides an interior fluid filled cavity capable of containing an indicia-bearing medium.

It is still a further object of the present invention to provide in a novel attachment device a free-floating indicia-bearing medium in said fluid filled cavity.

It is yet a further object of the present invention to provide in a novel attachment device a fixed indicia-bearing medium in said fluid filled cavity.

It is still a further object of the present invention to provide a novel attachment device in the form of a carabiner that provides an interior fluid filled cavity capable of containing an indicia-bearing medium.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Now referring to FIGS. 1-3, a preferred embodiment of the device 2 comprises essentially a body member 10, at least one openable gate member 20, at least one cavity 30 formed in the device 2 and a fluid 35 contained in said cavity 30. Device 2 optionally further includes an indicia-bearing device 40 contained in said cavity 30.

Body member 10 comprises an elongated member comprising a first end and a second end and is fabricated of any material suitable for attachment devices such as but not limited to bare or coated metal, wood, rubber or plastic or combinations thereof. Gate member 20 comprises an elongated member pivotally attached at one end to one end of said body member 10. The other end of gate member 20 contacts the other end of said body member 10 when said gate 20 is in a closed position. Now referring to FIG. 2, in a preferred embodiment gate member 20 is inwardly openable. Gate member 20 is fabricated of any suitable material as recited above for body member 10. In a preferred embodiment body 10 is curvilinear. In a most preferred embodiment body member 10 is formed in the shape of a carabiner.

Cavity 30 is formed in either or both of body member 10 and gate member 20. Cavity 30 may be formed of a depression or hollow in the material of body member 10 or gate member 20, for example where the material is formed of a nontransparent material such as metal, wood, rubber or opaque plastic and sealed with a transparent material such as but not limited to readily available plastics or acrylics, polycarbonates, polyimides, methacrylates, polystyrenes or the like such that the interior of the cavity 30 is visible. Now referring to FIGS. 2 and 3, alternatively, where the material of the portion of the device 2 wherein the cavity 30 is formed is a transparent material the cavity 30 can be a chamber formed therein by thermoforming, blow molding, boring or the like. Now referring to FIGS. 4 and 5, in yet another embodiment cavity 30 is formed between a portion of body member 10 and a transparent shell member 12.

Fluid 35 is any suitable substance that is nonreactive when employed in conjunction with the material of cavity 30. Suitable fluids 35 include colored or uncolored liquids such as but not limited to water, oil or gel or mixtures thereof, or, as seen in FIG. 2, small particulate matter 37 such as but not limited to colored or uncolored powders, grains or the like or mixtures thereof, and/or as also seen in FIG. 2 at 35 and 37 mixtures of liquids and solid particles. In a preferred embodiment fluid 35 is transparent. As is also seen in FIG. 2, those skilled in the art will recognize materials such as reflective or refractive material including but not limited to glitter and/or other insoluble material 37 may be included in fluid 35 for aesthetic purposes. It will also be recognized fluid 35 may contain a colorant. It is to be understood herein that each and every other of the embodiments of the other figures herein may also have the above particulate matter, glitter, etc. 37 within fluid 35.

Indicia bearing device 40 is contained in cavity 30 and may be fixedly anchored within said cavity 30 (as seen in FIG. 3B) or may be unanchored so as to be free-floating or free-moving within said cavity 30 (as seen in FIG. 3A). Accordingly indicia bearing device 40 may be fabricated of any suitable material that is nonreactive with fluid 35. Suitable materials are any materials capable of receiving indicia such as ink, engraving, paint, or the like and include but are not limited to metal, wood, laminate, plastic, cork, rubber and the like. Indicia bearing device 40 may have any configuration as long as such configuration can be received and contained in said cavity 30. Now referring to FIGS. 2 and 3 in a preferred embodiment indicia bearing device 40 is elongated and has a three dimensional cross section, providing more than one indicia bearing surface 42. As seen in FIG. 3, in one embodiment indicia bearing device 40 comprises three indicia bearing surfaces 42 and each surface 42 may for example bear different indicia.

In a preferred embodiment device 2 comprises a curvilinear body 10, body 10 comprises metal having at least one cavity 30 formed therein, said cavity 30 sealed by a transparent plastic material, said cavity 30 containing a fluid 35 comprising water and further containing indicia bearing device 40, wherein said indicia bearing device 40 is elongated and is free floating in fluid 35.

Now referring to FIG. 6 in a most preferred embodiment device 2 comprises a cavity 30 formed in gate 20 and body 10 is in the shape of a carabiner.

Now referring to FIG. 7, in an alternate preferred embodiment body 10 is in the form of a circle.

Now referring to FIG. 8, in a further preferred embodiment of the present invention, cavity 30 comprises a significant portion of the device 2.

As illustrated in FIGS. 7 and 8, device 2 is not limited to the form of a carabiner but may take any suitable shape or form.

While the preferred embodiments have been described and illustrated it will be understood that changes in details and obvious undisclosed variations might be made without departing from the spirit and principle of the invention and therefore the scope of the invention is not to be construed as limited to the preferred embodiment.
